T 0 all whom it may concer/n: A

Be it known that I, JOHN V. PEARSE, a citizen of the United States, and a resident of Owensboro, in the county of Daviess and State of Kentucky, have made certain new and useful Im rovements in Spraying Apparatus, of Whic i tion. l

My invention is an improvement in spraying apparatus and is designed especially for spraying plants upon ,railroad tracks with a liquid adapted to destroy the plants; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawings-Figure I is a top lan view, and Fig. 2 1s a side elevation part y in section of my improvements. Fig. 3 is a perspective view of the end of a car provided -with my improvements. Fig. 4 is a detail view of the spraying nozzle. Fig. 5 is a detail view of the strainer. Fig. 6 is a detail view of the stirrer, and Fig. 7 is a detail section on about line 7-7 of Fig. 1.

In carrying out my invention I employ a car which may in general respects be of ordinary construction and has the bed A upon which at its opposite ends I mount the tanks B, B, usually constructed to occupy each about one-third the length of the car7 leaving the remaining third between the tanks B and B and upon which lA mount a boiler C, a pump D connected with the boiler for operation by the steam therefrom7 an air reservoir E, an air compressor F connected with the air reservoir for establishing pressure therein and arranged for operation by the steam from the boiler C and for convenience I also prefer'to mount on the intermediate portion ef the car a speed indicator Gr which may be conventional and operated from the wheels in any ordinary manner, the said speed indi- -cator forming no part of my invention but being provided simply to facilitate the regu lation of the material discharged to -correspond with the speed at which the car is being moved over the tracks.

The tanks B and B are air tight and are provided with suitable openings closed by air tight covers II and through which access may be had to the tanks for any desired purose. For illing the tanks, pipes d and d earl from the pump to respectively tanks B and B and are supplied with suitable val-ves Specication of Letters Patent.

Application filed March 13. V1907. Serial No. 362.138.

the following. is a specifica- Patented Dec. 1o, 1907.

d2 and d3 S0 either tank may be sind independently of the other, thus enabling me to fill one tank while the other is being operated to spray the track. The pump D has pipes D andD2 leading in opposite directions and controlled by valves D3 and D4, said pipes D and D2 being in practice connected with any suitable auxiliary tank car that may vbe in train with the spraying lcar so the said auxiliary tank car maybe utilized at any time in tanks B and B so pressure may be established to any desired degree in the said tanks B and B in order to secure a uniform dis. charge from the tanks Without regard to the quantity of liquid that may be therein and the pipes e and e are provided with valves e2 and c3 so either of the tanks Bor B may be out out when it is desired t0 establish pressure in one tank only. I provide the tanks E with a pressure gage E and pressure gages E2 and E3, are preferably provided respectively on the tanks B and B to indicate the pressure therein. This idea of establishing pressure in the tanks is an important feature of my invention and while I prefer to establish it by the means described and through the compression of air it will be understood that steam pressure may be cstablished in these tanks from the boiler C by the means presently described and such pressure be utilized in Securing the uniform discharge of the liquid from the tanks without departing from some of the broad principles of my invention.

` Steam is supplied from the boiler C to the opposite tanks primarily for the purpose of heating the liquid in the tanks 'and thus cooking the contents thereof, but as before suggested the steam may be utilized in establishing the pressure in the tanks although it is preferred to employ the air as thereby the 'pressure may be established independently The air tank be desirablejin the use of the invention. As shown the steam pipes open into their respective tanks near the bottoms thereof and .communicate with stirring nozzles I preferably arranged centrally within the tanks near the bottoms thereof as best shown in Fig. 2 of the drawings. These stirring nozzles I are shown in detail in Fig. and comprise a body portion I and pipes I2 and I3 extending outwardly therefrom and made of dil'l'crent lengths and dellected laterally at their outer ends so that the discharge of steam from the pipes I2 and I will operate to stir the contents of the tanks and thus aid in securing a proper mixture of the ingredients of the destroying liquid and preventing, any clogging of the outlet inthe use of the invention as will be understood from the foregoing description and. accompanying drawing.

By the described construction it will be noticed I provide for iilling the opposite end tanks with water, for establishing pressure therein, for heating the tanks for cookingI the liquid therein and also provide for cutting out either tank so that one tank may be operating to discharge the liquid while the opposite tank is being filled and vice versa.

For discharging the liquid. from the tanks I employ the discharge pipe J leading from the tank B, and K leading fromthe tankB and these discharge pipes extend from their respective tanks downwardly below the bed of the car and thence longitudinally to the opposite end of the car at which point they communicate with the nozzle pipes L and M extending transversely across the ends of the ca'r below the coupling and supplied with nozzles N which may be constructed alikeand which will be hereinafter described.

The liquid passing to the discharge pipes is strained by strainers O within the tanks and these strainers fit over the ends of the pipes and are preferably made with an inner ,or body portion of .heavy wire O 'forming a frame and a covering of brass or other metal gauze O2, supported by the said frame and operating' eiectually to strain the liquid sov nothingl will pass to clog the nozzles connected with the nozzle pipes. The wire frame O is fastened to a collar O:g having a central opening O4 threaded on the inner end of the discharge pipe as best shown in Fig. 5 of the drawings. I

- The purpose of extending the discharge pipes J and K from their respective tanks to the opposite ends of the car is to enable the control of the valves J and K of said pipes .from the intermediate portion of the car,

which is eected by having the said pipes pass each other and arranging the valves J and K in proximity so their stems Jil and K2 may, extend up through the bed oll the car with their handhohls in convenient reach ol the operator on the intermediate portion el the car.- I thus arrange all of the controlling parts between the tanks where they may' be readily manipulated in the use of the invention.

lThe nozzles, of which any suitable number may be employed, are connected with thel transverse nozzle pipes and project down-v wardly withthe perforated heads l having any suitable number of spraying openings and provided at their upper. ends with necks 2 whichscrew into the lower ends of the couplings 3 and pipe sections 4 screw at their lower ends into the upper ends of the eouplings 3 and such pipe sections 4 screw at their upper ends into elbows 5 connected with the nozzle pipes by the valve casings 6 Whose vvalvesfmay be operated to independently control the several nozzles so any one `or more of the nozzles may be cut out without cutting out the others as may be desired in the operation of the invention. By the described construction it will be noticed that I am able to bring the nozzle heads close to the track and by using interchangeable pipe scctions i I may adjust the heads up or down to any desired distance from the track in order to secure the discharge of the liquid on to the plants from any suitable height.

In the operation of my invention it will be noticed the car is moved over the section of track from which the plants are to be removed and the liquid which may be any suitable liquid destructive to plant life may be placed or mixed in the 'tanks and its discharge from the tanks may be effected under any suitable pressure through the aid of the pressure devices before described and such pressure may be .independent of the quan- `tity of li uid in thetank or tanks so that any desired quantity ol liquid may be discharged per mile of track byregulatng the pressure in correspondence to the speed of thc car for which purpose speed indicators and pressure gages are supplied in order thatthe operator may regulate the ]n.essure and consequently the discharge olt liquid to agree with the speed of the ear.
